Allows programmatic registration of subflows needed by a flow execution being tested, see registerSubflow(Flow) . Subflows registered are typically stubs that verify parent flow input and output scenarios.

Also supports programmatic registration of additional custom services needed by a flow (such as Actions) managed in a backing Spring ConfigurableBeanFactory . See the registerBean(String, Object) method. Beans registered are typically mocks or stubs of business services invoked by the flow.
